I was just talking in general about the scope, buti t's on a 223 right now shooting 40grn v-maxs sighted in a 200. Dots line up all the way out to 600 with it, but for small targets at that range the circles don't really give me a precise aiming point. I can bust clay birds at 400 consistantly, but farther than that the circle is too big. I can adj the power to make the top or bottom of the circle the aiming point, but that takes too long to get on target and think where to aim.
